Thunder

Thunder and lightning are very impressive. You can just stand outside and watch the thunder and lightning going off. The lightning won't harm you; it just telling you stuff that you normally wouldn't hear from anybody. Then there are hurricanes, tidal waves and earthquakes that are more damaging. You don't want to mess around with those three, because they can kill people in a few seconds. If you're outside and there is some lightning going off, just walk right up to it and start a conversation with it.
You will not regret it. Some people say that lightning can harm you, but for me I know otherwise. It still can only harm you if you let it.
